NON REMOVABLE CAP FOR CONTAINERS.

Application led April 28, 1928.

My invention relates to a non-removable cap for collapsible metal tubes,which. tubes are adapted to contain such articles as cosmetics, drugs,food products, paint products,

cement and compressed products such as varions gases which are shippedunder compression and in fact any product having a viscosity which willpermit the same to be removed from a collapsible metal tube or anoncollapsible metal tube, as I desire it to be understood that myinvention may be applied to a rigid tube as well as to a collapsibletube.

A further object of my invention is to provide a non-removable cap forcontainer tubes which have their exit portion on the sidethereof and thecap heilig adapted to cover said exit portion or to be removed from oversaid exit portion.

Some of the objects of my invention having been stated, other object-swill appear as the description proceeds. when taken in connection withthe accompanying drawings in which,

Figure 1 is a side elevation of the upward portion of a tube showing mycap in closed position;

Figure 2 ure 1;

Figure 3 is a view similar to Figure 1 with the cap in raised position;

Figure 4 is a cross sectional view of a modified form of my invent-ion.

Referring more particularly to the drawings. the numeral 10 indicates atubular container having the neck portion 11. which neck portion has therestricted portion 12 and the upper end of this neck portion 13 isclosed and has the threads 14 thereon. In the portion 11 there is thehole 15 through which the contents ot the tube are adapted to bedischarged. Fitting over this neck portion .is the cap member 16 whichis closed atits upper end and has the crimped ring 17 therearound to litagainst the restricted portion 12. and the. upper portion 1S hasinterior threads for engagement with the threads 14 on the portion 13ofthe neck.

In Figures 1 and 2 this cap is shown in closed position while in Figure3 it is shown in raised position. and when in raised position thethreads 14 do not engage the interior is a cross-sectional view of FigSerial No. 273,726.

threads of the portion 18 and this allows the cap to slide upwardly onthe portion 12 until the projection 17 tits against the portion 13.

In Figure 4 I have shown a slightly modified form of my invention whichhas the tube 10 with the straight neck portion 21 with the enlargedupper portion 22 and the cap portion 24 has the crimp 25 therein whichfits against Ithe restricted portion 21 and prevents the cap 24 frombeing removed. This neck portion has the exitl hole 23 through which thecontained substance is adapted to be forced and has the raised threads27 disposed around the portion of the neck in which the hole 23 appearsand the interior threads 26 in the cap 24 engage the threads 27 to holdthe cap in ciosed position.

It is thus seen that I have provided a tube having a. non-re1novable capwhich is rigid and practically indestructible and which can be adaptedfor use not only on collapsible tubes but also 'on rigid tubes.

In the drawings and specitication I have set forth a preferredembodiment ot my invention, and although specific terms are employed,they are used in a generic and descriptive sense only, and not forpurposes of limitation. the scope of the invention being" set forth inthe appended claim.

I claim:

In a collapsible metal tube adapted to serve as a container for fluidsand the like, an extended neck portion, an opening in the base portionof the neck portion, a restricted portion to the said neck portion, anenlarged portion at the end of lthe neck portion, threads on saidenlarged portion, a cap adapted to t over the neck portion. interiorthreads in the cap portion adapted to engage the threads on the end ofthe neck port-ion, a restricted portion intermediate the ends of saidcap. said restricted portion being adapted to fit into the restrictedportion of the neck portion. the lower end of the cap being adapted toit over the opening to close the same when driven home, and therestricted portions permitting the cap to slide from over the openingwhen the threads in the cap are released from the threads on the neck.

In testimony whereof I affix my signature.

WILLIAM H. FRAMPTON.
